Braintree Payment Integration using PHP
Braintree offers a variety of products that make it easy for you to accept payments in your app or website. It makes sure your customers’ payment information is transported safely and securely.
Payment gateway
Braintree’s payment gateway will connect to all of the banking institutions and payment processors that need in order to collect money from your customers. You’ll give the payment information to Braintree, and they’ll let you know if the transaction was approved by the bank.
Braintree is renowned for having one of the easiest integrations your developers will ever complete – offering 3 client SDKs (software development kits) for both mobile and web platforms as well as server-side libraries in 6 common languages. While integration times can vary depending on your business, an experienced developer can complete a basic integration with Braintree in less than half an hour.
A sandbox account

As with any secure payment integration, you will first need to set up authorization. The Braintree sandbox allows you to set up a test environment to run transactions using test credit card numbers and explore the functionality of the Braintree gateway.

Client and server SDKs

Our client SDK enables you to securely collect payment information from your customers and the server SDK enables you to act on the collected payment information.

We have SDKs for the following client platforms and server languages:

  • Client SDKs for Android, iOS, and JavaScript
  • Server SDKs for Java, .NET, Node.js, PHP, Python, and Ruby
How it works

This diagram shows how your client, your server, and Braintree interact:

Step 1

Your front-end requests a client token from your server and initializes the client SDK.

Step 2

Your server generates and sends a client token back to your client using the server SDK.

Step 3

The customer submits payment information, the client SDK communicates that information to Braintree and returns a payment method nonce.

Step 4

Your front-end sends the payment method nonce to your server.

Step 5

Your server code receives the payment method nonce and then uses the server SDK to create a transaction.

Drop-in UI

Drop-in UI is a ready-made payment UI that offers the quickest way to integrate and start securely accepting payments with Braintree.

Quick, easy integrations

Quickly integrate Drop-in into your app or website’s checkout flow.

User-friendly, customizable UI

Customize the checkout form to meet your needs and fit your brand requirements.

Accept PayPal, cards, and more

Easily add new payment method types to your form.

Add the Drop-in UI

To load the Drop-in UI on the page, we’ll need to do 3 things:

1. Include the Braintree client SDK
2. Get a tokenization key
3. Add the Drop-in UI markup
Include the Braintree client SDK

 We’ll use the latest Braintree JavaScript SDK. Add the following code just above the closing </head>


<!– includes the Braintree JS client SDK –>

<script src=””></script>

<!– includes jQuery –>

<script src=”” crossorigin=”anonymous”></script>

Get a tokenization key

There are 2 ways to authorize the client to collect payment information:

client token, which requires a round trip to your server and enables you to use all of Braintree’s client API capabilities
tokenization key, which is a static key with reduced privileges that authorizes a subset of Braintree’s client API capabilities
Add the Drop-in UI markup

Drop-in UI consists of a small amount of HTML markup, which will be initialized using the Braintree JavaScript SDK we included above.

The paymentMethodNonce is a string returned by the client SDK. It’s a one-time-use reference to the payment information that your customer provided in your payment form.

<div id=”dropin-wrapper”>

 <div id=”checkout-message”></div>

 <div id=”dropin-container”></div>

 <button id=”submit-button”>Submit payment</button>



 var button = document.querySelector(‘#submit-button’);


   // Insert your tokenization key here

   authorization: ‘<use_your_tokenization_key>’,

   container: ‘#dropin-container’

 }, function (createErr, instance) {

   button.addEventListener(‘click’, function () {

     instance.requestPaymentMethod(function (requestPaymentMethodErr, payload) {

       // When the user clicks on the ‘Submit payment’ button this code will send the

       // encrypted payment information in a variable called a payment method nonce


         type: ‘POST’,

         url: ‘/checkout’,

         data: {‘paymentMethodNonce‘: payload.nonce}

       }).done(function(result) {

         // Tear down the Drop-in UI

         instance.teardown(function (teardownErr) {

           if (teardownErr) {

             console.error(‘Could not tear down Drop-in UI!’);

           } else {

   ‘Drop-in UI has been torn down!’);

             // Remove the ‘Submit payment’ button




         if (result.success) {

           $(‘#checkout-message’).html(‘<h1>Success</h1><p>Your Drop-in UI is working! Check your <a href=””>sandbox Control Panel</a> for your test transactions.</p><p>Refresh to try another transaction.</p>’);

         } else {


           $(‘#checkout-message’).html(‘<h1>Error</h1><p>Check your console.</p>’);








In this blog, We have described the Braintree Payment Integration using PHP.

Braintree comes with a JavaScript Client SDK offering many tools and feature to make this easy and quick. It offers two different possible integration: Hosted Fields and Drop-in.

The SDKs distinguish between nonces (single-use payment data collected from the client) and payment methods (vaulted payment data that may be re-used)

We have used in our projects Drop-in UI integration.

Thanks for reading!. We hope you found this blog helpful.
